SS5 Smart Valve Positioner

Brand: A-T Controls, Inc
Request Information
Perfect combination with reliable fail freeze function and smart performance with innovative durable coil drive.
Features
  • “Fail Freeze” Function to Help the Valve Stay at the Last Position on the Electrical Power Supply or the Pneumatic Supply Air by Accident 
  • Easy and Quick Auto-calibration 
  • Detects RA - Reverse Acting or DA - Direct-Acting Automatically Regardless of Wrong Air Connections 
  • Available to Use for Single or Double Acting without Any Special Adjustments 
  • Compact Design Allows Installation on Small Actuator 
  • Provides Error Messages Against Performance Failures 
  • Possible to Test the Actuator with Any Fixed Signal Under a Test Model 
  • Programmable Characteristic Curve with 17 Points 
  • Wide Operating Temperature Range -30° to 80° C / -22 to 176° F
  • Improved Control of High-friction Globe and Ball Valves by Eliminating an Overshoot and a Hunting 
  • Low Air Consumption 
  • Provides a Mounting Bracket to Meet IEC 60534-6-1 for Linear Valves 
  • Supports a NAMUR Mounting Pattern VDI/VDE 3845 / IEC 60534-6-2 and Provides a Multi-size Mounting Bracket for Rotary Valves
